WATER HEATER ATTACHIVEENT Application filed April 25,

The present invention relates to an improved connecting unit for a hot water sup ply system. i

The primary object of my invention is to provide a device which may readily be fixed to the boiler of a furnace in leak-proof manner without the use of any packing and screw bolts.

A second object is to provide a water distributing unit whereby the cold water flowing into a reservoir will be properly circulated through the boiler.

WVith these and other objects in View my invention consists in the novel construction, combination and arrangement of elements as will be hereinafter more fully described and shown in the accompanying drawings.

In the drawings in which similar reference characters denote corresponding parts:

Fig. 1 is a diagrammatic showing of my distributing or connecting unit in position of use;

Fig. 2 is a longitudinal section view of my device; and

Fig. 8 is a full section along line 33 of Fig. 2.

The heating system is of the usual type and includes the heating furnace having therein a boiler 10, water circulating tubes or heating units 11 mounted in the boiler and a reservoir tank 12 outside said furnace in which hot water is stored for use after passing through said circulating tubes in said boiler.

In order to afiord an easy means of connection of the circulating tubes 11 to the in coming cold water supply pipe 13 and also to the outflowing pipe 14: to the hot water reservoir, I provide my new distributing head or unit 15 which may be a hollow casting of brass, bronze or other suitable metal. The said unit is provided with an integrally formed partition 16 which divides the hollow interior into two entirely separate compartments A and B respectively. The front wall 15 of my unit is provided with two threaded openings 17 and 18 respectively, each communicating with one of said compartments. Similar threaded openings 19 and 20 are provided at the top and-bottom 1923. Serial No. 257,921.

faces 15 and 15 respectively. The rear wall 15 of my device is comparatively thick and may for instance have a thickness of one and a halfinches or more and is provided with a plurality of'holes 21, anequal number communicating with each of said two inner compartments A and B, said holes being regularly arranged in the said rear wall portion.

The rear wall portion 15 of my device is circular in section and is provided withthe ex ternal thread 22. Suitable threaded plugs 23 are provided and adapted to fit into any one of theholes 1720 inclusive.

My device is used as followsi The open ends of boiler water circulating tubes 11 are suitably mounted in the holes 21 as by brazing, or welding and then the member 15 is tightly screwed into'the wall 10 of thefurnace boiler. I ber 15 is of brass and threadedv no packing ofany kind is necessary to insure aleak-proof o1nt.- The cold water inlet pipe 13 from the reservoir tank12 is attached to opening 17 or 19 leading to compartmentA and the other one of'said two openings is sealed with a plug 23. The hot water outlet pipe 14 which also leads from the water reservoir tank 12 is attached either to opening 18 or 20 and the other one of said two openings is also sealed with a plug 23. The double set of openings to each compartment is for convenience of attachment of said pipes 13 and 14, the respective pipes being attached to the most accessible opening ofeach of the respective sets of the openingsin said two compartments. The circulation of water is as follows:

Since said mem-' Cold water flows through pipe 13into tion. I therefore, do not wish to be limited to the details shown and described.

What I claim. is

1. As an article of manufacture for a hot water supply system which includes a reservoir for hot water and heating units on the boiler of a heating furnace, a distributing unit for the inflowing cold water to and the outflowing heated water from said heating units to said reservoir, comprising a hollow copper alloy casting provided vexternally with a threaded portion adapted to screw into p the boiler of said furnace, and form a tight joint without packing by reason of the composition of said casting, a comparatively thickrear vwall to said casting, an integrally formed partition in the interior of said casting dividing said interior into two separate compartments, a plurality of uniformly distributed openings in said rear wall leading to each of said compartments for connection thereto of a plurality of heating units, and two sets of threaded openings in the other walls of said casting each set communicating with one of said compartments, one of each set being adapted to be connected with said reservoir when in use and the remaining ones not in use'being adapted to be sealed.

2. As an article of manufacture for a hot watersupply system having aboiler, a distributing unit for the inflowing cold water and outfiowing hot water comprising a hollow brass casting provided externally with a threaded portion adapted to screw into a wallof said boiler and make a tight joint therewith without packing by reason of the composition of said casting, a comparatively thick wall at one portion of said casting, an integrally formed partition in the interior of said casting dividing said interior into two separate compartments, a plurality of uniformly distributed openings in said thick wall leading to each of said compartments for connection thereto of a'plurality of heating tubes and two pairs of threaded openings in the other walls of said casting, each pair communicating respectively with one of said compartments, one hole of each pair being in, a different wall of said casting than the other hole-thereof in order that pipe connection to said compartments in said casting may be made tothe most convenient hole of each of said pairs and a threaded plug for closing the unused hole of each of said pairs.
